gravity and something else
3 forces gravity drag lift
As long as the book's velocity changes, there is a net forces acting on it - in other words, the forces are unbalanced. By the way ... How exactly does a book that is resting on a table slow down and come to a stop ?
The forces acting on a book could include gravity pulling it down, as well as any forces applied to it by external sources, such as someone pushing or pulling the book. Frictional forces may also be present when the book is in contact with a surface.
The main forces acting on you as you slide down a waterslide are gravity, which pulls you downward, and the normal force exerted by the slide, which pushes you upward. These forces work together to propel you down the slide at a controlled speed. Friction between your body and the slide also plays a role in slowing you down and providing a smooth ride.
When walking down the street, the main forces acting on you are gravity pulling you downward, normal force pushing you upward to support your weight, and friction between your feet and the ground providing the necessary traction for walking.
Abseiling is where you walk down a cliff/mountain attached to rope .
using a rope, it is called abseiling or rappeling.
(The term "abseiling" is equivalent to the French-based word used in the US : rappelling.) "The explorers entered the mine by abseiling down an empty elevator shaft."
Gravity is a force acting down on it. A normal force is acting perpendicular to the ground at the base of the structure.

While you're moving, the forces acting on you are unbalanced, and add up to something. When you're sitting, the forces acting on you are balanced, and add up to zero.
They clean the clock faces by abseiling down from above the clock.
